To all whom it may concern."

Be it known that' I, EDWARD LANDER HALL, a citizen of the United States, residing in New York city borough of Brooklyn, county' of Kings, an State of Newv York, have invented certain new and useful Improvements in Cameras, of which the following is a specification.

This invention relates to certain improvements in cameras," and has for its object to provide partitioning means of a simple and comparatively inexpensive nature, and of a nonl and improved construction, for dividing the interior of the camera boX into chambers or compartments adapted to be traversed by the cones of light from iiidependent lenses, in order that overlapping of the kimages thrown by thek respective lenses upon the plate maybe avoided when the camera is employed for stereoscopic work.

The invention consists, in part, in means of this generalyeharacter capable of convenient application to the. box'of a single lens camera, whereby A'the interior thereof ,may be divided vinto independent chambers or compartments capable of being traversed by the cones of light from independent lenses, in order that such cameras maybe quickly and conveniently adapted for use in stereoscopic w'ork.

The invention also consists, in part, in

l rpartitioning`v means especially adapted for use in connection with reflex' cameras, wherein such means comprises an adjustable partition member capable/of vmovement to permit Vthe interior of the camera box to be traversed by the mirror, when the saine is moved during focusing.

The invention also contemplates certain novel featuresot theconstruction, and combinations and arrangements of the several parts of the' improved partitioning means, whereby certain important `advantages are attained, and the said partitioning' means is rendered simpler, less expensive, and other- 1 wise better adapted andinore convenient for use, all as will behcreinaftcr fully set forth. Tl'ielnovel features of the invention will be carefully defined in the-claims.

ln order that my invention may be the' better understood I will now proceed to describe the same with reference to the accompanying drawings, wherein- Figurel is a fragmentary sectional view taken verticallythrougli'the box of a reflex camera showing the improved partitioning Fig@ is a fragmentary perspective view of certain of the parts illustrated in Fig. l., portions of the box being broken away to avoid"obscuringrhe partitioning means, and Fig. 3 is asectional view taken horizontally through the parts shown in Fig. l, the plane of the section being' indicated by the line in said ligure.

In these views I have shown my improvements applied for use in connection with a reflex camera but, while the partitioning means constructed'according to my inventiony is particularly well adapted forl eniployinent in suclrcameras, I do not desire to be understood as limitin j'myself to such use, sinc`e it 'will beobvious that thc improved partitioningmeans is capable of employment. with good results in connection `with cameras of various other types, and for such employment the said partitionin ieans may be varied, or modilied, within theA scope of the appended claims, as A`may be necessary or. desirable to accommodate the particular type or types of cameras to which the invention is applied.

A.In the drawings A. represents acamera box having` an interior chamber A1 adapted to receive a focal plane shutter, and B represents the well in front of said shutter chamber, normally closed at its top by a focusing mirror l, which, when in raised position, as shown in Fig. l, fits accurately upon the under-surface of an overhanging frame fitted aroundthe top of the well, so as to prevent leakage of light into said well, but is adapted, duringfocusing, to be dropped or foldeddown to an inclined position in order to reflect the image from the lens upon a ground` glass plate C1 above the well and, when in such inclined position, is'adapted' to fit accurately around its edgar portions,

upon an upwardly and rearwardly inclined surface 1Q, extended transversely across the base of the well, and-upon correspondingly inclined surfaces produced upon the side walls i8, 18 of thewell. y l

The base or door D of the well, in the sp cial form of camera herein illustrated, is lupported upon suitable uprights l0, and

comprises said transversely extended upwardly and rearwardly.' inclined part 1Q as itsv central ton' intermediate portion, a horizontal trout section 11. extended in front of said inclined intermediate portion 1:2,.and from which the latter rises. and a rear section 1?. which is iufined downwardly from the rear upper edge of -said intermediate section 1'2 toward the shutter chamber A above referred to.

F represents a lens chamber. which shown as separated t'rom the well B by a skeleton trame or partition l, and El reprcsents the lens box or cell. mounted for movement in said lensI chamber li. and pro. vided with a removable lens hoard or support 1.3. which. when the camera is desired t'or stereoscopic use. is fitted with dual lenses 1t. 1G. as clearly shown in Fig. 23 of the drawings.

14 represents a slotted opening produced in the hase or Hoor l) otl the well l, at the central part thereof` and extended from the t'orward section 11 through the intermediate aud rear sections 12 aud 12. and terminating adjacent to the shutter chamber A, and 14A represents an opening produced in the rear floor `support 1t), registering with said slotted opening 1l. as clearly shown in Figs. l aud 2. and along one side ot' said slotted opening 11 are extended guide strips or members 1T and lit. inc former being secured upon thc upper surface of the forward floor section 11. while the strip'oif mdmber 1Tn is secured upon the upper surface of the rear floor section 13. as clearly shown in Figs. 2 and As shown herein, the partitioning means comprises two insertible partition members 1S) and 2t). the member 19 being vertically extended above the central part (if the rear floor section 13, and being provided-with a laterally directed flange 22 extended along its lower edge and adapted to be slipped beneath the overhanging edge of the rear guide strip or member 17a. while its upper edge portion is provided with a similar laterally directed integral flange 9, capable of detachable engagement -above the endent flange ot a corresponding up )er gul( e strip or memberti, secured apon t e upper cross bar or member 1t)a of the 'camera box in alinement with said lower rear guide strip or member 17a. The rear edge of the rear partition member 1Q is vertically extended at the rear part ot' the well B so as to extend closely adjacent to the shutter within the shutter chamber A1, while the forward edge of said partition member is inclined/tp., correspond with the inclined forn'ardsurfVv faces of theside members 18;-18 of the well, so as to be adapted for accurate Contact upon the under surface of the mirror frame (l when the same is dropped into its-inclined focusing position.

The partition member 20 is vertically e2:n

'i rand 2 in order that said shutter tended above the 'forward floor section 11 of the well B in alinement with said rear member 19. and is provided at its lower` edge with an integral laterally directed flange 20, capable of detachal'ile engagement be neath the overhanging edge portion of the forward lower guide strip or member 17, so as to be effectively held in position thereby, its forward edge being vertically extended closely adjacent to the' lens` board 15, While. its rear edge 20" is shown concaved and so disposed as not to interfere with the free movement of the mirror frame C when the same is moved to and from its inclined focusing position. The improved partitioningr means as herein shown also comprises an adjustable shutter or partition member' 22, which as herein illustrated is made in a gcneral triangular form, being ofsuch dimensions as to be adapted to close the space between the forward inclined edge of the rear partition member 1f) and the rear concaved edge 20 of the forward partition member 20 when the mirror frame C is elevated into its horizontal raised position to close the top of the well during the interval of exposure. s shown herein. said adjustable shutter or partition member 22 is pivotally connected at its rear upper part, as seen at 23, with the rear upper partA of the rear partition member 19 an'd hasits forward and rear cdtfe portions Q5 and 2G, adapted, when thel said member is in operative position, to overlap and tit accurately upon the surfaces of the said forward and rear members Q0 and 19, while its upper edge is adapted to be extended closely adjacent to the under surface of the mirror fraaie C whereby it will be seen thatI the three members of the partitioning means afford au effective division of the well B into independent compartments alined with the respective lenses 16, 1G and adapted to permit the passage of the cones of light therefrom without. liability of leakage of light from one compartment to the other. whereby overlapping of the images upon the plate is effectively prevented.

24 represents a spring, one end whereof has connection with the rear partition mem ber 19, while its opposite end has connection with the adjustable or movable shutter or partition member 22 in suchla manner that the tension of said spring is exerted to hold the said shutter or partition member 22 normally in raised position, as shown in Figs. or member 22 shall bo automatically raised to closing Aposition when the mirror frame C is raiset during the interval of exposure. The lower edge portion of said shutter or partition member 22 is herein shown as normally engaged with the forward part of the slottedv ppening 14 when the said shutter or member is in operative raised posit-ion, and the structure and arrangement of the partais sach essere its spring 2li to the position showndu dotted lines in Fig. l, wherein` it stands during focusing.
